Solution Overview

Problem

Existing electrical enclosures are excessively large and inefficiently utilize space, requiring significant floor space and making maintenance and inspection of electrical bus members difficult due to their rear access design, which necessitates substantial spacing from adjacent structures.

Innovation Solution

An electrical bus member mounting system that consolidates electrical bus members within a single section of the enclosure, allowing for unobstructed front access and reducing the overall size of the enclosure, enabling it to be placed closer to adjacent structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If electrical bus members are disposed at the back of the enclosure requiring back access, then electrical apparatus can be housed within the enclosure, but the enclosure requires substantial spacing from adjacent structures and occupies excessive floor space

Engineering Contradiction:
Improveenclosure sizeVSAvoidaccess to electrical bus members
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent repositions the electrical bus members from the traditional rear location to the front of the enclosure, changing the spatial dimension of access. This allows maintenance personnel to reach the bus members from the front without requiring the enclosure to be spaced away from walls or other structures, thereby reducing the enclosure's depth and floor space occupation while maintaining accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the enclosure is spaced a significant distance from adjacent structures to provide back access, then electrical bus members can be accessed for maintenance and inspection, but valuable floor space is occupied

Engineering Contradiction:
Improveaccess to electrical bus membersVSAvoidfloor space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent inverts the traditional access approach by making the front of the enclosure accessible to electrical bus members instead of the back. This inversion eliminates the need for spacing between the enclosure and adjacent structures, allowing the enclosure to be positioned against walls or in tight spaces while maintaining full access for maintenance and inspection.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of manufacture

If electrical bus members are disposed throughout the available space behind circuit breakers, then electrical components can be arranged, but access is only provided through the back of the cabinet requiring substantial spacing

Engineering Contradiction:
Improvearrangement of electrical componentsVSAvoidaccess to electrical components
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent extracts the electrical bus members from their traditional rear position and relocates them to the front of the enclosure. This extraction allows the bus members to be accessed independently from the rear, eliminating the need for the entire enclosure to be spaced away from adjacent structures while maintaining the flexibility to arrange electrical components throughout the available space.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electrical bus member mounting system is provided for an electrical enclosure including a housing having a front, a back and a plurality of sides, a plurality of sections disposed between the sides, at least one electrical apparatus disposed within a first one of the sections, and an electrical bus assembly electrically connected to the electrical apparatus. The electrical bus member mounting system includes a mounting assembly having a first portion and a second portion. A plurality of electrical bus members are coupled to the first portion and the second portion is coupled at or about at least one of the sides of the housing within a second one of the sections thereof. Accordingly, the electrical bus member mounting system consolidates a substantial portion of the electrical bus assembly at a single location within the second one of the sections of the housing, in order to facilitate access thereto.
